To allwhom tm/ay concern:

Be it 'known' that I, LEwIs J. `K IN'GsLEY,'a

citizen ofthe United States, residingat Bing'- hamton in the county of-Broome and State 5 of New York, have invented certain new and useful Improvements in Reducing-Presses, of which the following isa'specification The object of mysaid invention is to produce a press in which Iboth motions of thereciprocating die structure shall be utilized, thus making it possible for a press to do double the usual amount of Work.

This invention is especiallyapplicable to that class of presses by which metallic cup` like structures are made, such as cartridgeshells, shaft-tips, ferrules, and thelike; and in the form shown it consists, generally speak-A ing, 'of a reciprocating die-carrier with two female dies, a stationary male die located upon each side thereof, one upon one side and the other upon the other side ofthe center of the machine, and mechanism'gwhereby the product from onepair of diesjisv automatically' transferred to the other'pair of dies; by which the operation is continued.

It further consists in certain details of construction Vand arrangements ofparts, as will be hereinafter S more particularly vdescribed and claimedyfl` 'desire itfunderstood,fhow ever, that'th'e parts maybe transposed and numerous other'changes may be made' with'- out departing from my invention.

' 'Referring to the accompanying drawings, which are made a part hereof and ,on which similar lettersandgures offreference indicate similar parts, Figure l is atop or plan view of a machine embodying my said invention; Fig. 2, a side elevation thereof; Fig. 3, a longitudinal vertical sectional view as seen from the dotted line 3 3 in Fig. l; Fig. 4, a transverse sectional view as seen from thev dotted line 4451 Fig. 5, a detail sectional View as seen from the Adotted line 5 5 in Fig. 4, and Fig. 6 adetailsectionalview on` the dotted 45 line 6 6 in'Fig. 4.

- In-saiddrawings1the portions markedA represent lthe `main A,fran'nework of the ma` chine; B, therdri-ving or crankshaft; (Lfthe'V reciprocating die structure; D D the station? -5o ary dies; E, a gripper-carriage yhaving suit! I :sable grippers for transferring the partly-finished blanksfrom one die tothe other, and F a shaft for operating said carriage. i

. The frame A, as is necessary in machines of this lcharacteiyis heavy and rigid and in most sizes of machines is composed mainly of a single casting. Itis peculiar in form, having heavy ribs (terminating in points a) which pass underneath and up behind heavy transverse bars'A, which carry the stationary dies 6o D and D. Beyond those projections a which are nearest the crank-shaft the frame sides are recessed or cut away to permit the passage of the cross-head, which will be presently described. It then rises up to the appropriate height to serve as bearings for the shaft B.

The shaft B is mounted in the bearings therefor on the frame A. 'It has a pulley b, through which it is driven by a belt from some suitable source of power. (Not shown.) 7o

Onthe opposite -end it has a bevel gear-wheel b', which, through a similar gear-wheel f', drivesthe'shaftF. Centrally, it is formed `into acrank'fand drives the pitman B.

i The reciprocating die-carrier@ preferably carries the two female dies "c'land c andis itself carried by heavy side bars C', Vwhich eX- t'end, outside the frame portions at to alongside the cut-away portion" of ,thel frame and thence passinwardly andare connected to 8o therocking head B2 on the end of the pitman B' by a 'rod or shaft C2, which passes through both. .The consequence f is j that when the shaft B revolves the die structure C and the dies whichfit carries are 'reciprocated The 85 form of theside pieces Cf is best shown in Fig. 4, where they arefshown as resting in the bearings in bracket-like projections A2 on the frame A, being heldinvplace by caps a2, as shown. In the arrangement shown the fe- 9o male dies c and c are fixedly attached to or formed integrally with this die-carrier C, and ginany event the die-opening is'co'ntinued by meansfof Aal perforation entirely through the structure which carries the female dies. In operation in a machine constructed in accordance -lwith'my inventionvv ajndj arranged ',as shown "they article `being operated ponis thist' pla'ced onor in front of the die D'and by it forced through the female die c and car- 10o ried by the following article being formed through the die-carrier to its opposite side. As it emerges from the hole in the die-carrier it is seized by the mechanism about to be described and by it carried to in front of the female die c' in position to be operated upon by the male die D at the same time the reciprocating die-carrier is receding from the die D. As above stated, this results in a duplication of the use of the machine, so that it performs twice as much work as a press having but a single motion.

The carriage E is mounted upon suitable ways on the reciprocating die-carrier C and lnoves longitudinally of said carrier, but transversely of the machine. Said carriage contains a rock-shaft E, upon which are suitable gripping-fingers land 2,which are adapted to grip the article being formed as it emerges from the orifice in the die-carrier C behind the female die c and transfer it to in front of the female die c. These grippingfingers, as is best shown in Fig. 4C, are adjustably mounted and one or both (preferably the lower one) is in the form of a spring, so as to yield somewhat in use. The carriage E is attached, by means of a connecting-rod E2, to a vibrating arm E3, which in turn is mounted on a rigid arm C3, carried by the reciprocating die-carrier C, and is moved back and forth by said vibrating arm, as will be presently described. The shaft E has an arm 3, which is rigidly attached thereto and projects out therefrom alongside a fiat fixed surface on an adjacent portion of the carrier, and thus said shaft is permitted to revolve just ninety degrees and no more, so that in its movement in carrying one of the unfinished articles from one die to the other said article will be exactly turned end for end. For the purpose of revolving this shaft as it is pulled sidewise through the link Il?, I provide a spur-pinion 4, which engages with a rack-bar 5 on an adjacent rigid portion of the carrier, the effect being, of course, that as the carriage E is pulled sidewise said shaft will be revolved in its bearing. It is necessary, however, that the travel of the carriage should be greater than is required to revolve the shaft the distance permitted. The pinion et is therefore not rigidly connected to the shaft, but is held thereon by friction between suitable washers w, bearing against said pinion upon one side and non-revolving parts upon the other sides. The necessary travel is thus permitted, while more than ninety degrees revolution of the shaft is prevented. It is also necessary that the gripping-fingers shall be pulled sidewise away from the article being formed, and thus retreat out of the way of the dies before said dies have completed their work. I therefore, as shown in Fig. Li, provide a catch 6, which extends out around behind the arms 3, behind which said arm will pass as the carriage E reaches the end of its travel, and which will prevent said arm and the shaft E from revolving until said arm has escaped from said catch, the frictional engagement of the spur-pinion -f permitting such movement.

The shaft F is driven from the shaft I3 by means of the bevel-gears D and f2 It bears a cam F', which is kept from revolving thereon by means of a spline f, but is permitted to travel longitudinally of the shaft and said spline as the reciprocating die structure travels, as will be readily understood. This shaft is specded at exactly the same speed as the crank-shaft, and thus the surface of the cam driven thereby can be arranged to operate regularly and uniformly in relation to the stroke of the reciprocating die-carrier. The cam comes in contact with an appropriate bearing-point on the vibrating arm E3 and thus, through the link E2, operates the carriage E. This cam maybe connected so as to operate said vibrating arm in both directions, or a spring S may be provided to operate it in one direction while the cam operates it in the other, as shown.

The operation of my machine maybe briefly recapitulated as follows: An article to be formed is placed by any appropriate means on the point of the male die D. As the reciprocating die-carrier C approaches it said article is forced into the female die c and thence through said die-carrier and presently emerges therefrom on the other side. Itis there taken by the gripping-fingers and transferred by the means described to in front of the female die c', which by that time is approaching the male die D. As the engagement takes place between these dies and the article being formed, the gripping-iin gers are withdrawn sidewise in the manner described and returned to in front of the opening behind the female die c to repeat their operation.

I have shown and described a machine in which two of the die-carriers are stationary and one is adapted to reciprocate. It would obviously be a mere reversal of parts to have the intermediate die-carrier stationary and the others reciprocate. I have shown the intermediate die-carrier as bearin g the female dies. It would also obviously be a mere reversal of parts to have the intermediate die-carrier carry the male dies and the end die-carriers carry the female dies. In each case these changes of course would require some rearrangement of mechanism; but such rear rangements are obviously within the skill of an ordinary mechanic and of course within the scope of my present invention.

Having thus fully described my said invention, what I claim as new, and desire to secu re by Letters Patent, is-

l. The combination, in a press, of two male and two female dies, mechanism whereby they are caused to approach and recede from each other alternately, one pair of dies being arranged to operate at one end of the stroke,
